A thermal interface material may be covalently bonded to a bottom surface of a heat dissipating device andor a backside surface of a heat generating device. The switched capacitor bridge is configured to sample first and second reference voltages twice per unit time interval. As a result, the tape bonded onto the end surface of the honeycomb structural body can be accurately processed by the laser. The supramolecular complex comprises the perturbant non-covalently bound or complexed with the biologically active agent. The exposure control system is arranged to adjust the X-ray detector to a low spatial resolution during the test exposure and to a high spatial resolution during the X-ray exposure.
